Abstract (en)
[origin: US2017373403A1] A full-duplex 2×2 multiple-input multiple-output (MIMO) antenna array is provided. An antenna reflector defining an x-y plane provides a plurality of antenna elements on the reflector. The linear polarization elements of the antenna elements are arrange in orthogonal polarizations for each transmit and receive pair. The elements are aligned in the same direction for half the orthogonal pair. A pair of elements are aligned along an axis to provide two coupled phase offset signals at a third element. The third element is collinear to the element of the first element defining a line of symmetry and parallel the direction of the element of the second element. The antenna array provides improved isolation between orthogonal ports and between transmit and receive ports by providing coupled signal cancelling between ports. This technique also increases boresight radiated pattern gain, as an additional benefit.
